A polymer-bound refill for writing, drawing and/or painting devices, in particular for pencils or coloured pencils, including at least one binder, at least one wax, at least one colouring agent and at least one filler. The refill includes polylactide as binder.

Refill for writing, drawing and/or painting devices and method for the production thereof

An eraser for removing strokes of writing, painting and/or drawing implements, including at least one binder and at least one plasticizer, wherein the at least one plasticizer is a polyol ester.

Eraser

A writing, drawing, marking and/or painting utensil or cosmetics implement or input device for contact-sensitive surfaces, wherein the utensil/implement/device includes at least one shank element made of plastics material or a plastics-containing wood substitute. The at least one shank element has a surface, or in that the at least one shank element has a surface which is sheathed in a material layer having a cover surface. The surface of the shank element or the cover surface of the material layer is in the form of a haptic and/or non-slip layer. The haptic and/or non-slip layer has a structure formed in one piece with the shank element and/or the material layer. The structure is formed by corrugation.

Writing, drawing, marking and/or painting utensil or cosmetics implement or input device for contact-sensitive surfaces, and method for producing the same

Pencil

The invention relates to a component for writing, drawing, painting and/or cosmetic implements for receiving at least one application medium, the component comprising at least one sleeve, which is made of a polymer-bonded wood substitute substance and which has an inner sleeve wall and an outer sleeve wall, the component further having at least one migration blocking layer, the at least one migration blocking layer directly or indirectly covering the inner sleeve wall of the at least one sleeve.

Component for writing, drawing, painting and/or cosmetic implements and method for the production thereof

A writing, drawing, painting or cosmetic device having at least one honeycomb body formed from a plastic material and/or a composite material consisting of a natural material and a plastic material. The at least one honeycomb body contains a plurality of hollow longitudinal structures that are axially parallel to one another.

Writing, drawing, painting or cosmetic device comprising a honeycomb body, and method for producing the honeycomb body or the device comprising a honeycomb body

The invention relates to a pencilfor writing, drawing, painting and/or cosmetics purposes, comprising a colored coreand a core holder enclosing the core, wherein the core holder comprises a wood-replacement materialwhich encloses the core, wherein the coreand core holder are retained such that they cannot be displaced in relation to one another, wherein the core holder has a carrying sleevewhich encloses the wood-replacement material, and wherein the modulus of elasticity of the carrying sleeveis equal to, or higher than, that of the wood-replacement material and the bending strength of the carrying sleeve is higher than that of the wood-replacement material.

Writing, drawing, painting and /or cosmetics pencil and method of producing the same

A pencil that includes a polymer-bonded lead, a polymerbonded wood substitute material that includes an organic filler and covers or surrounds the lead along its length, and an adhesion promoter layer disposed between the lead and the wood substitute material. The lead and the wood substitute material each have a polymer. The polymer in the lead being incompatible with the polymer in the wood substitute material so that the polymer of the lead and the polymer of the wood substitute material do not create any connection with one another. The adhesion promoter layer is connected to the polymer in the lead and to the polymer in the wood substitute material so that the adhesion promoter layer forms a connection with the polymer in the lead and with the polymer of the substitute material. The organic filler is formed by particles having a maximum particle size of 250 &#x3bc;m.

Writing, drawing, decorating or cosmetic pencil

A polymer-bound writing substance for writing, drawing and/or painting tools, particularly for pencils or colored pencils, including at least one polymer bonding agent, at least one wax, and at least one filler material, wherein the writing substance is further provided with 0.1 to 5 wt % of palm kernel oil, and/or coconut butter, and/or coconut oil, and/or oleic acid.

Writing substance for writing, drawing and/or painting tools

A polymer-bonded pencil lead for writing, drawing, and/or painting devices, including at least one polymer binder, one wax, and at least one filler. The pencil lead includes 0.5 to 2.5% by weight palm oil.

Pencil lead for writing, drawing and/or painting devices

The invention relates to a wood substitute material for wood-encased pencils, comprising the following ingredients: 15-3.0% by weight of at least one polymeric binder, 50-80% by weight of at least one organic filler, 0-20% by weight of at least one inorganic filler, 0.5-5% by weight of at least one adhesion promoter, 1-30% by weight of at least one wax, 0-10% by weight of at least one color pigment, and 0-10% by weight of at least one additive, the at least one adhesion promoter forming a chemical bond between the at least one polymeric binder and the at least one organic filler, a ratio of the at least one adhesion promoter and the at least one wax in the range from 1:2 to 1:6 being formed, and the sum of organic and inorganic filler being not more than 80% by weight.

Wood substitute material and its use

An unburnt color lead for writing devices, drawing devices and painting devices, includes at least one coloring material, at least one binder, at least one organic lubricant which is solid at room temperature, and at least one filler material whose particles essentially have a disk-shaped configuration. The color lead contains 20 to 80 weight % of the at least one filler material, and the color lead contains at least 20 weight % hexagonal bornitride as a first filler material.
